Four world records fell on Saturday (30 May), day two of the IPC Athletics Grand Prix in Nottwil, Switzerland, as the Netherlands’ Marlou van Rhijn (T43), Italy’s Martina Caironi (T42), and Finland’s Toni Piispanen (T51) all smashed their own 100m world records, and Canada’s Becky Richter broke the 26-year-old 100m T51 mark.

Under pouring rain and heavy humidity, Diane Roy (Sherbooke, Que.) aggressively led the women’s race the entire way until edged at the finish line by Australian Angela Ballard, who finished in 3:59.20.
